I have a 128GB SanDisk MicroSD card which I formatted on my laptop, placed in my 640, which then ran me through whether I wished to save files to it. I stated no for all of these questions, and then transferred around 30GB of MP3 files to that card via a USB connection to the 640 into the music folder.
All of these files had been converted to MP3 and checked for corruption with a few different programs. Then, when I go to listen to the music I can only see about 1/4 of the music I uploaded to the card. Then only about 10% of the music is available as it keeps coming up with an error code for most music.
Then, after a reboot of the phone the sign comes up to say that the card is corrupt and unreadable. When I put the card back in the laptop it seems fine, and everything is playable off of it.
I have repeated this several times and it keeps doing a similar thing. Please help. What is up?
